Breaking Points in Quartic Maps
M. Romera, G. Pastor, M. -F. Danca +3
Dynamical systems, whether continuous or discrete, are used by physicists in order to study non-linear phenomena. In the case of discrete dynamical systems, one of the most used is…
Finding Attractors of Continuous-Time Systems by Parameter Switching
M. -F. Danca, M. Romera, G. Pastor +1
The review presents a parameter switching algorithm and his applications which allows numerical approximation of any attractor of a class of continuous-time dynamical systems depen…
A New Lorenz System Parameter Determination Method and Applications
A. Orue, G. Alvarez, G. Pastor +3
This paper describes how to determine the parameter values of the chaotic Lorenz system from one of its variables waveform. The geometrical properties of the system are used firstl…
Breaking projective chaos synchronization secure communication using filtering and generalized synchronization
Gonzalo Alvarez, Shujun Li, F. Montoya +2
This paper describes the security weaknesses of a recently proposed secure communication method based on chaotic masking using projective synchronization of two chaotic systems. We…
Cryptanalyzing an improved security modulated chaotic encryption scheme using ciphertext absolute value
G. Alvarez, F. Montoya, M. Romera +1
This paper describes the security weakness of a recently proposed improved chaotic encryption method based on the modulation of a signal generated by a chaotic system with an appro…
Cryptanalyzing a discrete-time chaos synchronization secure communication system
Gonzalo Alvarez, Fausto Montoya, Miguel Romera +1
This paper describes the security weakness of a recently proposed secure communication method based on discrete-time chaos synchronization. We show that the security is compromised…
